[movies]The 3D Web
As web designers tried to make the internet look more like the "real" world, they experimented with three dimensional online environments. This program looks at several early examples. Mark Pesci explains VRML, the virtual reality modeling language. Chris Stuart demonstrates blacksun.com, a web site that uses VRML technology. Annette Louden demonstrates construct.net, an online environment for building VRML sites...

[texts]Trailing Vortex Measurements in the Wake of a Hovering Rotor Blade with Various Tip Shapes - Martin, Preston B.
This work examined the wake aerodynamics of a single helicopter rotor blade with several tip shapes operating on a hover test stand. Velocity field measurements were conducted using three-component laser Doppler velocimetry (LDV). The objective of these measurements was to document the vortex velocity profiles and then extract the core properties, such as the core radius, peak swirl velocity, and axial velocity...

[texts]Stochastic Modeling of Laminar-Turbulent Transition - Rubinstein, Robert
Stochastic versions of stability equations are developed in order to develop integrated models of transition and turbulence and to understand the effects of uncertain initial conditions on disturbance growth. Stochastic forms of the resonant triad equations, a high Reynolds number asymptotic theory, and the parabolized stability equations are developed.

[texts]Exponential Formulae and Effective Operations - Mielnik, Bogdan
One of standard methods to predict the phenomena of squeezing consists in splitting the unitary evolution operator into the product of simpler operations. The technique, while mathematically general, is not so simple in applications and leaves some pragmatic problems open. We report an extended class of exponential formulae, which yield a quicker insight into the laboratory details for a class of squeezing operations, and moreover, can be alternatively used to programme different type of operati...

[texts]Experimental and Calculational Studies of the Interactions of BF3 with Fluoroethers - Zehe, Michael J.
BF3 was co-condensed with (C2H5)2O, (CF3CH2)2O and (C2F5)2O in excess argon at 15 K. Infrared spectra of the matrices showed a definite Lewis acid-base interaction between BF3 and diethyl ether; a weak but definite interaction with bis(2,2,2,-trifluorodiethyl)ether, and no observable interaction with perfluorodiethyl ether. Molecular orbital (MO) calculations complemented the experimental observations by revealing that fluorine atoms on the ethers decreased electron localization about the oxygen...

[texts]Global Interferometric Skin-Friction Measurements on a Wingtip Model - Zilliac, Gregor
Skin-friction distribution on surfaces of flight vehicles is desirable for several reasons. Aerodynamicists would like to know where transition occurs and if separation is present. Turbulence modelers are interested in validating skin-friction (drag) predictions. Finally, if it were possible to sum the skin-friction distribution on a lifting wind tunnel model, it would be possible to determine the viscous contribution to the total drag, a quantity not readily measured independently of the induce...

[texts]Verification and Analysis of Formulation 4 of Langley for the Study of Noise From High Speed Surfaces - Farassat, F.
There are several approaches to the prediction of the noise from sources on high speed surfaces. Two of these are the Kirchhoff and the Ffowcs williams-Hawkings methods. It can be shown that both of these methods depend on the solution of the wave equation with mathematically similar inhomogeneous source terms. Two subsonic solutions known as Formulation 1 and 1A of Langley are simple and efficient for noise prediction...

[texts]Chemical Alteration on Mars Indicated by the Iron-Manganese Ratio - Yen, A. S.
The Alpha Particle X-ray Spectrometers (APXS) onboard the Mars Exploration Rovers (MER) have measured the chemical compositions of over 400 samples on the surface of Mars. Fe and Mn are among the elements which are well established by this instrumentation. Fe 2 and Mn2 have nearly the same ionic radii and distribute similarly in primary igneous rocks, maintaining a consistent Fe:Mn ratio. Upon exposure to an oxidative weathering environment, Fe 3 and Mn4 are commonly formed, and elemental fracti...

[texts]Temperature dependence of the biaxial modulus, intrinsic stress and composition of plasma deposited silicon oxynitride films - Harding, David R.
Silicon oxynitride films were deposited by plasma-enhanced chemical-vapor deposition. The elemental composition was varied between silicon nitride and silicon dioxide: SiO(0.3)N(1.0), SiO(0.7)N(1.6), SiO(0.7)N(1.1), and SiO(1.7)N(0.%). These films were annealed in air, at temperatures of 40-240 C above the deposition temperature (260 C), to determine the stability and behavior or each composition. the biaxial modulus, biaxial intrinsic stress, and elemental composition were measured at discrete ...
